uPVC windows in Hackney
uPVC window frames are made from extruded profiles with several internal chambers that trap air and slow heat loss. Larger frames, and those on exposed elevations, are usually reinforced with steel or aluminium inside the profile so they stay straight and the locks keep engaging properly over the years.
In England, replacement windows on a house that look similar to the originals usually do not need planning permission. Flats and maisonettes do not have permitted development rights for replacing windows, and listed buildings, conservation areas and homes under an Article 4 direction may need consent, so check before ordering.
When windows are replaced in England, Approved Document F expects the room's ventilation to be no worse than before. That usually means trickle vents in the head of the new frames, sized to the room, so the glazier records whether the old windows had vents and specifies the new ones to suit.
uPVC frames need washing a few times a year with warm soapy water and a drop of light oil on hinges and locking points. Drainage slots along the bottom of the outer frame let rainwater escape, so keep them clear of dirt and leaves to stop water collecting in the cill.
Included as standard

About Hackney for this job
- Postcodes covered
- E5, E8, E9, N4, N16 and the surrounding area, including Stamford Hill, Islington and Stratford
- Coast
- Hackney is well inland, around 31 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Hackney the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. uPVC frames are bulkier than aluminium, so they take a little more glass area from small windows. On south and west elevations, solar-control or neutral low-E glass limits overheating, while north-facing rooms benefit from high light-transmission glass and warm-edge spacers that reduce condensation.
- Access and setting
- In terraced streets and flats, old frames are usually removed and new ones fitted from inside to avoid scaffold. Parking for the van, access through communal areas, leaseholder consent and the lack of permitted development rights for flats all need checking before ordering.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Approved Document F covers ventilation. Replacing windows should not leave a room with worse background ventilation than before, which is why replacement windows often include trickle vents.
Choosing your uPVC windows
Woodgrain and colour foils
Grey, black, cream or woodgrain foils on one or both faces, so the frames can match a door or suit an older house.
Georgian or astragal bars
Bars set between the panes or applied to the faces of the glass for a traditional divided-pane look.
Double or triple glazing
Low-E double glazing suits most homes; triple glazing adds a third pane for lower heat loss and quieter rooms, but units are heavier.
uPVC Windows in Hackney: questions
Should I choose double or triple glazing?
Well-specified double glazing with low-E glass and warm-edge spacers can meet the energy standard for replacement windows, and the certified rating confirms it. Triple glazing adds a third pane, which helps on cold, noisy or north-facing elevations, but the units are heavier and need frames designed for them. We can quote both so you can compare.
Do I need building regulations approval for replacement uPVC windows?
Yes. In England, replacement windows are controlled fittings, so the work must meet building regulations. An installer registered with a competent person scheme such as FENSA or Certass can self-certify the work and you receive a certificate; otherwise approval comes from building control. Wales, Scotland and Northern Ireland run their own systems, and we explain which route applies before work starts.
Can I fit uPVC windows myself?
You can, but the work still has to meet building regulations. In England and Wales, without an installer registered with a competent person scheme you need building control approval and inspection. Accurate measuring, correct packing, fixing and sealing all affect weather performance and how the locks work, and mistakes are hard to put right because frames are made to size and cannot be returned.
Do new uPVC windows need trickle vents?
In England, usually yes. Approved Document F expects ventilation after window replacement to be no worse than before, which normally means trickle vents in the new frames. Our glaziers record the existing ventilation at survey and specify vents to suit each room. Rules in the other UK nations differ, so the detail is confirmed for your address.
